REDUCTION OF PRODUCTION CYCLE TIME OF WIND TURBINE BLADES

For any manufacturing industry, cycle time optimization is very important in order to maximize the production capacity with the effective use of time. The objective of this project is to calculate and analyze cycle time of main moulding process of wind turbine blade of 50 meters and above length. The time analysis was made by noting down start and end time of each event in moulding process. The time analysis data, which was taken, was transferred to excel sheets and Gap analysis and Pareto charts were drawn. Based on the data gathered, delay time was analyzed for each event in the process and also the key factors which caused the delay was found. The result obtained from the chart can be used to reduce the key factors which caused the delay in the production time. From the data collected and analyzed, it can be concluded that the major delay reasons in the main moulding process is due to layer missing from MPRP (Material preparation), repairs, x-shell induced delay. Humidity is also found to be a major contributor to delay in monsoon.
